ReviewCeramic on ceramic hip prostheses: a review of past and modern materials.
Ceramic on ceramic hip prostheses are an increasingly popular choice for hip replacement. Modern manufacturing techniques and developments have increased the strength and reliability of ceramic materials. The alternative bearing couples such as metal-on-polyethylene and metal-on-metal are more inclined to wear and produce particulate debris. Despite reports of fractures and stripe wear, harder, more inert and more wear resistant, modern ceramic-ceramic hip replacements provide a strong alternative to traditional bearings.

Review Case ReportsSubtalar dislocation: two cases requiring surgery and a literature review of the last 25 years.
Subtalar dislocations are uncommon, representing ~1% of all traumatic dislocations. We present two cases of closed medial subtalar dislocation and a systematic literature review of the last 25 years. ⋯ 4.

Randomized Controlled TrialUni- and bipolar hemiarthroplasty with a modern cemented femoral component provides elderly patients with displaced femoral neck fractures with equal functional outcome and survivorship at medium-term follow-up.
The choice between unipolar and bipolar hemiarthroplasty for treatment of displaced intracapsular femoral neck fractures in elderly patients still remains controversial. Our objective was to compare series of elderly individuals with a displaced femoral neck fracture treated with either a cemented, modular unipolar or bipolar prosthesis with the same femoral component. ⋯ Unipolar hemiarthroplasty group had a significantly higher dislocation rate when compared with bipolar hemiarthroplasty group. However, both provide elderly patients with equal ambulatory ability and low revision rate at medium-term follow-up.

Comparative StudySubchondral insufficiency fracture of the femoral head in males.
Subchondral insufficiency fracture of the femoral head (SIF) has been reported to be observed mainly in the elderly osteoporotic females and most of the studies on SIF have been made based on female patients. The purpose of this study is to document the clinical characteristics of SIF observed in male patients. ⋯ SIF in male is observed mainly in their 40s, and their prognosis seems to be good as compared to that in females.

Clinical TrialOrthogeriatric care pathway: a prospective survey of impact on length of stay, mortality and institutionalisation.
Care pathways for elderly hip fracture patients are increasingly implemented but there has been only limited evaluation of their use. Our objective was to investigate the impact of such a care pathway on the use of healthcare resources and on patients' outcomes. ⋯ A care pathway for elderly hip fracture patients allowed decreased LoS without affecting mortality or change of residential status 1 year after fracture compared to prefracture baseline.
